Useless temporaries are also emitted for PAD and ORDER optional arguments:
program main
integer :: i, k, l, m, n
real :: e1, e2
real, dimension(4,5) :: b
real, dimension(5,4) :: c
b = reshape([(i, i=1,20)],[4,5])
m = 5
n = 4
c = reshape(b, [m,n])
e1 = 1.0
e2 = 2.0
k = 2
l = 1
c = reshape(b, [m,n], [e1,e2], [k,l])
end program main
